The WHO says it's the leading preventable cause of death and that tobacco kills more than five million people every year. Yet in some countries smoking is gaining in popularity.

It's the leading preventable cause of death. Tobacco kills more than five million people every year.

More and more countries in the West have banned smoking in public places. In Paris the law came into place just last year but already some restaurants have found ways around it, installing smoking rooms. For these smoking rooms there are strict criteria as to how many times the air has to be changed and how many people are allowed occupy the space.

With no such rules in Senegal, the smoking market is booming. The cigarette remains a status symbol there and the country has seen a sharp rise in the number of people, particularly women, taking up the habit.

HEALTH will also be showing you a myriad of ways you can kick the habit, from accupuncture to the simple solution of drinking three glasses of water whenever the nicotine urge hits you. HEALTH visits a hynotist who says that two or two and a half hours is all that is needed to re-teach your brain about cigarettes.

Meanwhile French doctors have made major medical advance in terms of lung transplants. They are now able to transplant lungs that aren't in premium condition. Up to now, over 80% of lungs donated were deemed unusable.
